4.4 Language extension compatibility: intrinsics

Note:

The following table lists some of the commonly used intrinsics that are
supported by Arm Compiler 5
and shows whether Arm Compiler
6 supports them or provides an alternative. If there is no support Arm Compiler 6, you must
replace them with suitable inline assembly instructions or calls to the standard
library. To use the intrinsic in Arm Compiler 6, you must include the appropriate header file. For more
information on the ACLE intrinsics, see the Arm® C Language Extensions.

Note:

This is not an exhaustive list of all the intrinsics.

The intrinsics provided in <arm_compat.h> are only
supported for AArch32.
